Tb all whom it may concern 'Be it known thatJAMns Giinxnn, a citizen of *the United States, residing .at Houston, in the county "'of Harris and State of Texas, has invented certain new anduseful Improvements in a Pneumatic Disk Gin, of which the following is a specification." r

The object of the invention is toprovide a device of the character described which has been particularly designed for ginning fibrous material, such as seed cotton. Another object of the invention is to provide a gin of the character described, embodying stripper disks, arranged to co act with stripper bars, or blades, the cotton being held by pneumatic suction against said disks, and by them carried into contact with the blades, whereby the lint is stripped from the seed, preparatory to delivery to condenser (not shown); 4 Another feature of the'invention resides in the provision of means for receiving the lint cotton from the disks and deliverii'ig the same to the delivery flue for conveyance to said condenser. s p V A still further feature resides in the provi- 'sion of-suitable air tubes, or fines by means of which pneumatic suctionis created for holding the seed cotton against the stripper disks and for conveying the lint cotton from the gin when it has been stripped from the seed.

Withthe above and otherobjects in view, the invention has particular relation'to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings,

'wherein:

7 Figure 11 shows a fragmentary sectional riew of the inlet end of the delivery chute.

Referring now more particularly to the drawings, wherein like-numerals of reference designate similar parts in each of the figures the numeral 1 refers to the framework, which has the supporting legs 2, 3 and 1. The framework 1 has the aligned bearings 5, 6 and 7, in which the diskshaft 8 r0,-

tates, and fixed upon this shaft, and spaced apart, are the perforated stripper disks 9. Supported by the framework and arranged behind said disks are the suction pipe 10, and the convcyer pipe 11, the latter being The section 10 of the suction pipe lO'has a swivelling connection with the adjacent sections, permitting said section to turn, and said section is formed with a plurality of suction flues 12, whose free ends are arcuate in general contour to fit between the corres sponding disks 9 and rest upon the shaft 8. The section 11 of the conveyor pipe is likewise connected to the adjacent sections with swivelling connections to permit the turning of said section 11, and this section is formed -with conveyor chutes 13, whose free ends creating a suction of air through the sucdisks, and is delivered from it through the spaced hoppers to the disks. These hoppers are arranged alternately, with respect to the suction flues 12, and oppositely, with respect to the chutes 13 and through them the seed cotton is fed into the disk spaces between the suction fines 12'. The shaft 8 has a pulley 16 fixed thereon, through which rotation is imparted to s'aid'shaft, and the disks, carried thereby, in the direction indicated by the arrows, in Figures 4 and 5.

The cotton is held against the sides of the I tightened, clamping said sections 1n fixed disks, between whichit is fed, by. the suction of the air, through the perforations thereof, and is carried by said disks against the blades 17, located between said disks. These blades project between said disks and their edges fit closely against the inner sides of the adjacent disks. *Said sides of said disks are provided with radiating arcua-te grooves 13, which engage with the cotton and tend to forceit outwardly to distribute it along the full length of the blades to provide for the maximum stripping effect thereof. The blades 17 are supported by a transverse bar 19, whose ends are formed with depending arms 20, 20,- whose lower ends are'pivoted to the front legs 3 and 4. The upper ends of these arms have aligned circular openings 21, 21, through which the shaft 22 extends.

This shaft is mounted in the aligned bearings 23, 2 1 and 25, carried by the framework and has eccentrics 26 carried thereby and located in the openings 21. The shaft 22 has a pulley 2'7 fixed thereon in alignment with a pulley 28, fixed on the shaft 8, and a belt 29 operates over said pulleys and transmits rotation from the latter to the former, and the shaft 22 is thereby rotated. The rotation of the shaft 22 oper'ates,'through the eccentrics 26, to oscillate the arms 20, and the blades 17, carried thereby, the oscillation of the blades rendering them more etticient in stripping the lint fromthe seed and preventing the congestion of the cotton against them. 7 j

The blades rest upon the supporting fingers 30, spaced apart and formed integrally with thebar 19 and are clamped thereon by means of caps 31-,triangular incross section, V

and secured in place bymeans of bolts'32, 32, which pass through said caps andblades and are tapped into the fingers underneath. As the edges of the blades become worn, causing too much clearance,itbecomes necessary to adjust them and to provide for this adjustment the blades are formed of the set bolts 36 are threaded and the inner ends ofthese bolts rest against the plates 38, which in turn rest against theouter ends of the corresponding blades. When the edges of the blades wear, causing too much' clearance between them and the-disks, the

Op- -posite the outer ends of the blades the bar 19 has the upstandingears through which bolts 32, 32 may be loosened and the-Set bolts screwed against the plates 38, which will force the blades inwardly, and the slop- 4 mg sides 34: of i the openings 33', acting against the bolts 32 will cause the blade sec-' tions to spread apart until the desired clearance is attained andthe bolts 32,. 32 then position.

As above stated, the-cotton fed between the stripper disks is held by air suction against the sides of the disks and carried by them against the edges of the blades, by which the seed are arrested and the lint passes on between the disks and the blade edges, the lint being stripped from the. seed by the combined action of the disks and oscillating blades. During this operation,

.the seed work out along the sides of thecaps 31 in the troughs formed by the sloping sides of said caps and the adjacent disks and when freed oi? the lint they are no longer subject to the airsuction, and pass over the blade bar 19 into a suitable receptacle provided for them.

The free ends of the delivery chutes 1 3 are provided with side-slots 39, 39 through which the lint enters into said. chutes. These inlets, asis'obvious, are restricted, to in crease the force of the suction to insure the entrance of the lint therein. After the lint is carried-by the disks past the ends of the.

suction flues 12 it passes beyond the range of the suction through the disk perforations and comes within range of thesuction through the chutes 13 and is free to enter into said chutes through which it is carried into the conveyorpipe, and any lint I which may be drawn throughthe perforations of the disks passes through the fines 12 into'tlie suction pipe, and said lint is then cenveyod by said pipes, by. suction, to the condenser. 1 I I As stated,-'the'sections 10" and 11' are rotatable so that the fiues 12: and chutes 13 may be withdrawn from between the disks 9', as shown in dotted. lines, in Figure 4,

thus making provision forgaining access to i the for repairing or cleaning the same.
